Most LED light panels have a mix of something like 2800-3000K and 4800-5000K.
If you look up the specs of some commercial lights, this would give you an idea as to what they use.
I doubt the home style E27 LED globes would have anywhere near the right spectrums for plant growth, they are mainly designed for people to read the newspaper by, not grow killer buds!
Just because they are LED bulbs does not mean they are suitable LEDs to grow plants with, not all LEDs are created equal.
Good on you for trying DIY and having a go, but I bet you will end up buying a proper commercially made LED in the future.....so you may as well just get it over with and buy a proper light straight up.
Save up and get the best one you can afford.....as they say....."buy once, cry once"!
